Javascript Images : Preloading Images

There is always some delay involved while downloading
images from the server, and on slow networks the delay is even more prominent

This issue can be resolved by using an Image() Constructor, which enables you to preload images, and
put in browser's cache before it is put to use. This caching technique vastly improves the response time.

Even the size of the cached image(width and height) can be set,
but the Image() constructor must be kept in the head element only.
